Motor control device

A motor control device that controls a motor using a reluctance torque, the motor control device comprising:

• a first setting unit configured to set a motor torque command value which is a command value of a motor torque which is to be generated from the motor;
• a rotation speed detecting unit configured to detect a rotation speed of the motor;
• a second setting unit configured to set an armature current command value and a current phase angle command value based on the rotation speed and the motor torque command value;
• a current vector setting unit configured to set a d-axis current command value and a q-axis current command value based on the armature current command value and the current phase angle command value;
• and
• a drive unit configured to drive the motor based on the d-axis current command value and the q-axis current command value,
• wherein the second setting unit is configured to set the armature current command value and the current phase angle command value such that an armature current vector which is set based on the d-axis current command value and the q-axis current command value is included in an area surrounded by an armature current vector locus in maximum torque/current control and a vertical axis in a d-q coordinate system with a d-axis current on a horizontal axis and with a q-axis current on the vertical axis.
